CHANDELIER AND FIXTURE.

Specification of Letters Patent.

Patented Nov. 26, 1912.

Application filed January 6, 1912. Serial No. 669,777.

To all wlwm it may concern:

Be it known'that I, WILBUR H. FISHER, a citizen of the United States,residing at Conneaut, county of Ashtabula, State of Ohio, have inventedcertain new and useful Improvements in Chandeliers and Fixtures, ofwhich the following is a specification.

My invention relates to chandeliers and fixtures intended to carryelectric lights, and its object is a novel fixture possessing variousadvantages.

Fixtures of the general type with which my invention is speciallyconcerned comprise a body or junction part intended to be supported froma ceiling or a wall and a plurality of arms or branches extending fromsaid body part and supporting electric lamps.

My invention comprises various features of construction and variouscombinations and arrangements of parts, etc., which can best bedisclosed through the description of a fixture embodying it.

While the chandelier hereinafter described represents the bestform orembodiment of my invention at present known to me, so that many of itsspecific details are important on account of their specific advantages,yet the invention is not confined to such details, but presents featuresof a more broadly novel character which will appear hereinafter and willbe particularly indicated in my claims.

Although my invention can be embodied and applied in electrical fixturesof various sorts, I have herein shown and described an electricalfixture designed for the use of electricity only.

In the accompanying drawings, Figure 1 is an elevation of one style ofchandelier, one of the arms being shown as withdrawn therefrom, andseveral of the other parts being shown as displaced from their ordinarypositions or broken away in order t( make apparent features which wouldother wise not appear. Fig. 2 is an elevation of a somewhat differentstyle of chandelier, various parts being broken away to show theinterior construction, and a part A associated with one of the arms beinshown as withdrawn from its ordinary position. This style of chandelierdiffers from that shown in Fig. 1 as re rds features connected with itssupport,-t e differences being such as specially adapt it to be arrangedclose to the ceiling. Fig. 3 is a view of the junction part or body B ofthe chandelier shown in Fig. 1 as seen from beneath when the part Lshown in Fig. 1 is out of the way, the fixture being turned 30 degreescounter-clockw se from the position shown in Fig. 1. Fig. 4 1s aperspective view from above, partly in section at a plane correspondingto the line 44 in Fig. 3, showing various parts comprised in the body,some of the parts being separated from one another in order that theinterior conformation and arrangement may be visible, and the parts Sand I being shown as cut or broken away for a like purpose. Fig. 5 is aplan view showing the lower of the parts I appearing in Fig. 4 whollyremoved from most of the other parts there associated with it, and inits entirety. Fig. 6 is a fragmentary section at a plane corresponding,say, to the line 66 in Fig. 3, showing an arm in position in one of thearm-holes in the body, certain of the parts shown in Fig. 3 beingomitted. Fig. 7 is a plan view illustrating a modification of the partsshown in Fig. 5; and Fig. 8 is a diagram illustrating the arrangement ofelectrical parts according to this modification. Fig. 9 is a perspectiveview of certain of its parts removed from an arm; Fig. 10 is aperspective view of some of the same parts when removed from a sleeve inwhich they are inclosed in Fig. 9;'Fig. 11 is a section through the partA on a plane just above the upper edges of the parts A in Fig. 10illustrating the form and arrangement of the parts shown in Fig. 10; andFig. 12 is an enlarged detail view showing the manner in which a wiremay be attached to one of the parts A shown in Figs. 9, 10 and 11.

I will first describe in a brief way some of the general features whichare common to the chandeliers shown in Figs. 1 and 2. It is to beunderstood, however, that except as indicated the whole of the followingdescription applies to both these styles offixture. As shown in Figs. 1and 2, a chandelier of either of the styles illustrated comprises ajunction part or body proper B, removable arms A, and additional partsby which the chandelier is supported. The junction part or body B hasholes or sockets 6 adapted to receive and support-the arms A; and thebody and the arms comprise electrical circuits, and also contact meansfor combining these several circuits so as to form electricalconnections for the lamps when the arms ml in )lace intli'e arm-ho es;and. provision is ma e so thatwhen'inserted binthebody fluthe caseaccidental disp acement of the arms. may be prevented by suitableengagement of the arms in the arm-holes to keep them from turning andsuitable locking means adapted to secure them against-being withdrawn.lVliile the arm contacts may serve for the engagement of thearms in thebody to prevent them from turning, or as a looking means to preventtheir withdrawab'or both, it-is pre erable' to make other or additionalprovisions for this purpose, articnlarly if the arm contacts have theiighly advantageous form of yielding metallic members a projecting fromthe ends of the arms as shown at the right in Fig. 1.

I will now describe how the body B may be constructed for both theillustrated styles of chandelier, and the manner in which it is mountedand supported in each of them. As will be seen from Fi s. 1 and 2 thebody It comprises a part I w iich carries contact means with which thecontact means on the arms are engaged when the latter are inarms arereceived and engaged so as to pre-" vent the arms from turning. Thenecessary insulation of the contacts and other electrical parts is bestsecured by making the part. I itself of insulating material, in whichcase it may be desirable to secure it to a metallic member Y. As shown,the part I is in closed by a shellor shrouding S, so that/ since theterm body alone may be under f stood as referring either to thismnerjunc tion part. I or to the junction part or body B as a whole-thepart I may be distinguished as the inner body. The shroudin S not onlyforms an ornamental easing junction part I, but also comprises outerportions s of the arm-holes or sockets b,- whieh portions may serve inthe securing of the arms against withdrawal and may be internallythreaded (as shown) for this purpose. The holes a may be made relativelyargc so as to allow the projections a on the arms to pass them lliieeasily. As shown, the interior )art has eight converging sockets i whici are arranged with 30 and degree spacing (see Figs. 4 and 6), so thatby the use of the )roper ones a chandelier having two, three, our, orsix equally spaced arms can be constructed; but for the sake ofuniformity of ap earance the'shrouding is nevertheless 'ma e with"twelve "equally As shown, the 'arins-,-are-- not.

or thespaced holes a and the four blind ones closed byornamental screw.plugs 13 (see Figs l,

'2and 3),.as also the others at any time not in us'e.'

.,The-.meinber Y to which the insulating inner body I is secured (seeFigs. 1, 3 and 4) is preferably not. a portion of the casing orshrouding S, but a separate part (made, for exam le, of cast iron). Thepart S, however ias an inwardly extending flange s (see Fii. 4) which isclamped between the parts i and the lower side of the part I. The part Sis definitely alined in proper position with respect to the other partsby the screws-or bolts Y which serve'to secure the part- I to the partY, these screws passing'through holes in the flange a and extending onup through holes i in I to engage nuts (not shown) which rest in an ulardcpressions in the upper side of I. 'ashers z of any suitable material(as card board, for exam le) may be placed between the inner body 'andthe flange 8'. -\Vhen the part I is made of porcelain or any other moreor less frangible material, the member Y is useful to-reinforce andbrace it, as well as in other ways which will presently a )pear.

Inthe style of chandelier and the construction shown in Fig. 1, there isafoot F (of cast iron, for example) which is adapted to'be "secured tothe'ceiling, this foot having a portion which fits into the hollow partf and is secured therein by a cotter pin f", and

the part in turn fitting into thehollow stem .or standard X and beinglikewise secured therein by a cotter pin The current supplywires 10which pass down from the ceilmg through the standard X'enter throii h aole'in the side of the part f. lVhen-t e chandelier is fully assembled,the foot. and

the associated parts are covered by the threepart cam py C, which isheld in place on themember by a set screw 0. There are also a part I)(held in place on the standard X by set screw (1) and a bottom shellpart I (held in place by screws Z that. enter holes yin a rim 3 on thepart Y) which serve a purpose similar to t wt of the cano y The standardX extends down through the hole 1" in the inner body I (see Fig. 4), and

its lower end fits into the hub of the part Y and is secured therein bythe cotter pin (see Figs. 1 and 3). When the part D is brought down soas to fit over the rim 3 on the upper edge of the shrouding S andsecured in place, it helps to make the body ll firm and rigid withrespect to the standard. In the construction shown in Fig. 2, thereare'lilt'ewise a foot F and a stem X; but the stem X'is threadeddirectly into the foot and the wires 10 are arranged outside of thestem, and both the stem and the foot. are in closed by the two-partcanopy C and the part D, which fit directly together as shown.

.The stem X extends through the hub 7 as well as through the inner bodyI, and on its lower end is threaded a nut N which clamps the part C andD between the body roper and the ceiling. The bottom shell is arrangedand secured just as in Fig. 1.

I will now proceed to describe in detail a construction and arrangementof the inner body I and the electrical parts and connections associatedwith it which are e ually adapted for both the styles of chan eliershown, also indicating the particular arrangement of the inner body Iwith respect to other parts that may be preferred in each style. As willbe seen from Figs. 1 and 6, there are at the inner end of each of thesockets 2' in the inner body I two inwardly extending chambers i whichare in effect prolongations or extensions of the socket and serve toreceive the contacts a which project from the ends of the arms A. In thearrangement shown, (see Figs. 4, 5, and 6) the contact means carried bythe inner body I are arranged centrally with reference to the sockets iand are completely inclosed in it and when an arm is in place in asocket they lie between the arm contacts a and. are engaged with them at2" in the chambers i, opposite or adjacent the inner end of the socketproper,--preferably in a manner hereinafter described. For the sake ofcombining strength, simplicity, and the best insulation, it ispreferable that both the outer portion of the body I which contains theconverging sockets z' and the central part which contains the contactmeans be of insulating material, and that the outer and central portionsbe integral. The body I may, however. advantageously comprise partsseparable through the center where the contacts are arranged and thechambers 2'' located in a direction transverse with respect to thesockets. As shown (see Figs. 4 and 5) the body is made in two parts Ieach of which contains part of each socket i and its grooves 2" togetherwith one of the chambers 2" opening into the socket, and alsoaccommodates the contact means exposed at 2' in the chambers i lying init; and the two parts are exact duplicates of one another. The wall orpartition 11" by which the chambers 2" associated with each socket areseparated may consist of insulating means interposed between the halvesI of the body, and, in particular, of a portion of a flat annular memberI of vulcanite, fiber, or any suitable insulating material, (see Figs. 4and 6) inclosed between the halves, the abutting faces of the two halveshaving broad, shallow annular depressions or grooves i to accommodateit. The contact means exposed at i in the chambers i in the severalhalves may advantageously be arranged between their juxtaposed faces inpassages, depressions, or recesses at the bottom of the grooves 2'. As

shown in these figures, the depressions have themselves the form ofannular grooves 1'. each made up of a number of short curved grooves,and two annular members or rings I constitute the contact means: thuswhen the arms are put in place in the sockets they will all be connectedin parallel between these two contact members whose engaging portions iassociated with each socket he in the path of the contact means on anarm as it enters the socket. Each of the members I may be formed of apiece of fairly large copper wire bent to shape, and its currentconnection may consist of a portion of the wire bent so as to extendradially outward from the ring in an extension of the groove 11 to thehole 17 just beyond the edge of the shallow annular depression i Herethe wire is bent at right angles to the plane of the ring and attachedto one of the supplv wires w referred to above. In the case of thecontact member I lying in the lower half of the body I, this portionextending at right angles to the plane of the ring or annular portionand the attached supply wire w pass down through the hole 1' in the samehalf. In the case of the contact member I lying in the upper half, thisportion and the attached supply wire 10 do not pass through the hole 2'in the upper half at all. but instead pass down throu h the heel i inthe lower half, this hole lying 120 degrees from the hole 2' in thelower half. The fitting together of the two halves I in any but theproper manner with the holes 2' in them 120 degrees apart is insuredagainst by two dowels 1' and two corresponding holes 2' with which eachhalf is provided.

In the case of the construction shown in Fig. 1, the part I from whichthe wires 1/ issue will preferably lie next the part Y and form thelower half of the body I, as just described, and the wires 11: will bebent upward through the hole 6 so as to pass up through the standard X.\Vith the construction shown in F ig. 2, however, the inner body I willpreferably be secured to the part Y in a manner just the reverse of theabove, so that the part I from which the wires issue will lie away fromthe part Y and form the upper half of the body I, and the wires w willnot be bent to pass through the hole 2, but will extend directly upwardto the ceiling.

I will now describe the construction shown in Figs. 7 and 8, whichindicate how the parts I of the body and the contact means carried bythem may be modified and arranged so that a series connection of thearms can be obtained. It will be understood, however, that the form ofthe parts I shown in Fig. 7 is equally adapted for a parallel connectionof all the arms by the form of contact means just described. As shown inFig. 7, the holes i and i in each half of the body are replaced by apair of holes 2' and i" and corresponding approximately radial grooves,and there are also two additional pairs of such holes and grooves. Thereare also a lurality of notches i in the outer edges ot the grooves i.The contact means in the grooves i consist of a plurality ofelectrically isolated sections or seg ments, the ends of these contactsections being bent outward so as to lie in the notches 5" or in radialgrooves not otherwise'occupied and keep the sections in their properplaces. Insulating pieces may, if desired, be placed in the groove 2'between the contact sections. As shown, the sections are ar ranged toproduce a series connection of the arms in the sockets marked I, II,III, and IV. Of course only the contact sections 1", I and I in thelower half of the body appear in Fig. 7; but in Fig. 8 the contactsections I and I in the upper half and their arrangement with referenceto the chambers i and the sections I", I, and I in the lower half arediagrammatically indicated. (It will be understood that where the uppercontact sections overlap the lower ones cir' cumferentially they willmost naturally be arranged directly above them instead of in therelative radial positions which for clearness of illustration the linesrepresenting them occupy in Fig. 8). At each arm current passes from anupper contact section to a lower contact section, or vice versa, as willbe readily understood; and in each of the contact sections except thetwo terminal sections I and I the current passes from one arm to thenext arm. By a slightly different arrangement of contact sections it iseasy to adapt the fixture for two, three, or six serially connectedarms; and it is also easy to obtain a connection of various arms inseries parallel or parallel series. Of course not all the holes 2' and2' or their radial grooves are needed for the four-arm seriesarrangement illustrated, nor all the notches z' those not shown as inuse being intended to provide for other arrangements and connections ofthe arms.

I will now, finally, describe the chandelier arms A, first setting forththeir external features and the manner of their insertion in the bodv,and then their internal features and construction. Reference has alreadybeen made to the projections a which prevent the arms A from turning inthe sockets, and it will readily be observed (see Figs. 1, 5. and 6)that in consequence of the proportions and arrangement of the partsthese projections make it impossible to insert an arm very far in asocket except in one or two POSltlUlS 180 degrees apart. It will also beobserved that before the contacts a on an arm can approach the portionsi of the confacts I which they engage in a socket the projections a mustbe in the grooves 2" and the insulating partition 2" must be between thecontacts a, so that the short circuiting of the fixture or injury of thecontacts that might otherwise result from the careless introduction ofan arm askew is safeguarded against. As it is advantageous that theyielding contacts a be not merely pressed against the contacts I (withwhich, as shown, they engage laterally) when the arms are in place inthe sockets but rather in definite gripping or interlocking engagementwith them, these contacts a may be made quite resilient and may have thebent form shown in Figs. 6, t), 10, and 11. Then as an arm is pushedinto a socket the diverging ends of these contact springs will first beforced apart by the 0011- tacts I and then come together of themselvesso that the contacts I will rest inthe sharp angles of the springs justbeyond their diverging portions, and the parts will thus be retained andlocked in the relative positions shown in Fig. (3. Of course theengagement of the contacts a and I in this manner of itself tends toprevent the arms fromturning; but it is obviously preferable not tosubject the contacts to strain of this kind, but rather to provide theprojections a and grooves 1" already described. It is preferable alsonot to rely entirely upon the spring contacts a as cure the arm againstwithdrawal from the socket, but to provide additional locking means. Forthis purpose an externally threaded collar .A' may be screwed into theouter portion a of the arm-hole after the arm has been pushed home so asto engage the projections a on the arm and thus positively prevent itswithdrawal (Figs. 1 and 6).

Referring now tothe construction and internal features of the arms, theprojections 0 which co-act with the collar A as above described mayconveniently consist of tongue-like portions punched from the metal ofthe arm and bent out-ward as shown in Figs. 5 and 6. The projections anext the end of the arm may consist of the protruding ends of a pin A(Fig. 5) which extends through the arm and serves to hold certain partsin place within it. As shown in Figs. 9, 10, and 11, the parts withinthe arm comprise an insulating sleeve A (of vulcanite or insulatingfiber, for example) pierced with two holes a (one not shown) whichserves as an insulative lining in the end of the arm, a pair of metalstrips A whose free ends form the spring contacts a, two wires A whichare attached to the other ends of the strips A and conduct the currentto the lamps carried by the arm, and a a locking means to seflat-sidedinsulating part A (of porcelain or other suitable material) laterallyrecessed at one end and having a shallow groove a across the other end,and also pierced with a hole a. The strips A are bent to conmums form tothe sides of the insulatin piece A and overlap its end somewhat in t egroove a", so that when these parts are assembled (Fig. 10) and insertedin the rather tightfitting sleeve A till the end of the insulating pieceA is about flush with the end of the sleeve (Fig. 9) they are firmlyheld in proper position, and it only remains to insert the sleeve in thearm so that the hole a and the holes a in the sleeve register with theholes in the arm and to secure all the parts in place by means of thetight-fitting pin A The wires A may be secured to the ends of the stripsA which lie in the recesses in the part A in various Ways, thatillustrated in Figs. 10, 11, and 12 being very simple and efi'ectlve. Ashere shown, the end of each strip somewhat resembles a fishs tail. Theextreme end has a fork-like form and is bent up, as shown, and two finswhich project from the narrow portion of the strip near the extreme endare also bent up to form a trough in alinement with the fork. The wireis laid in the trough and extends through the fork, and the sides of thetrough are squeezed together upon it. If desired, the joint may be madestill more secure by the application of solder.

The lamp sockets may be attached to the arms in any preferred orapproved manner.

The advantages of the chandelier construction which I have described arenumerous. In the case of the style of fixture shown in Fig. 1, the bodyB with the stem X attached and the arms A can be wired in the factoryand sent out as individually complete and independent standard parts insubstantially the condition in which they are shown in that figure,-thepart D being of course fastened down in its normal position against thebody,and the canopy C and the bottom shell L can likewise bemanufactured as independent standard parts. In order to assemble andinstall this style of fixture, it is then only necessary toattach thefoot F to the ceiling and set the canopy C in the usual manner, tofasten the bottom shell L in place with its two screws l, and to insertthe arms in the body and lock them with their screw collars A. In thecase of the style of fixture shown in Fig. 2, the body B can be sent outwith the part D very much in the shape in which it appears in Fig. 2. Inorder to assemble this style of fixture, it will then only be necessaryto attach the foot F to the ceiling, put the body B and the part D inplace with the canopy C above them, screw the nut N on the standard Xbeneath the hub y of the part Y until the parts are firmly clampedbetween the top of the body and the ceiling, and fasten on the bottomshell L and insert and secure the arms as before. None of the parts ofeither style of fixture require much space; and any of them can bepacked for shipment :in very small bulk, either together or separately.Again, a fixture of any desired number of arms,-two, three, four, orsix,-can be built up by simply unscrewing the proper plugs B from thebody and inserting the arms, and the number of arms can be altered withequal facility after the fixture has been installed for years. From avery small number of different standard parts of each kind a greatvariety of designs can be produced, and fixtures already installed caneasily be altered in design as desired. The fixture is simple and strongin construction, and its parts are likewise few and simple, so that theycan be very easily and cheaply manufactured. All the parts comprised inthe arms and in the body B can be assembled expeditiously and cheaply.When the arms and the body have once been made up and tested in thefactory, it will hardly ever be necessary to take them to pieces, forthere is nothing about them to reak or get out of order; and if after afixture has been installed and in use one of its arms should needrepair, it can be sent back to the factory for this purpose withoutremoving or dismantling the fixture, or even rendering it unsightly.
